Description

[Technical Field]

[0001] The present invention relates generally to centrifugal fluid pumps, and more particularly to pumps that are driven integrally with the housing and utilize reduced-size flow paths to conserve energy and reduce cavitation.

[0002] This application claims priority to a U.S. provisional patent application (Serial No. 62 / 944,702) filed on December 6, 2019. The filing date is December 7, 2020 due to December 6, 2020 being a weekend. [Background technology]

[0003] Typical pumps currently available on the market are divided into two categories: centrifugal pumps and positive displacement pumps. Each type in this category has distinct characteristics that distinguish them from the other. The present invention, in contrast, incorporates features of both. The present invention is unique in that the pump and pump housing rotate on the same axis, differentiating it from other fluid pumps. Currently, no product similar to the present invention exists on the market. With the present invention, the faster the rotational speed, the greater the flow rate (gallons per minute (GPM)) and flow pressure generated. The pump of the present invention can operate without cavitation at speeds ranging from 1,000 to 100,000 rpm (revolutions per minute). In contrast, conventional centrifugal pumps are limited to a rotational speed of around 3,500 rpm due to cavitation issues.

[0004] To compare the present invention with conventional pumps, all pumps are compared at the same level, assuming they do not have pressure relief valves, and are left powered on and unattended. ● In a typical centrifugal pump, even if the fluid stops flowing during operation, the pump continues to operate, stirring the fluid in the housing / volute and causing cavitation and recirculation. Increasing the rotation speed here results in no fluid flow and no increase in pressure. This is a phenomenon that occurs when the pump / impeller rotates independently of the housing, creating a gap around the impeller and causing the liquid to slosh. The result: Under high load conditions, there is a large loss of energy and no work is done. Positive displacement hydraulic pumps (gear pumps, rotor pumps, diaphragm pumps, piston pumps) use the power of a drive motor to push liquid out. When the flow stops, the drive motor locks up and stops rotating. This happens because the physics of liquids is such that they cannot be compressed. The result: a large loss of energy, damage to the motor, and no work being done. ●If the fluid inside the pump of the present invention stops, fluid lock does not occur, and the pump continues to rotate with no flow, but pressure continues to increase as the rotation speed increases. The energy effect of using the pump of the present invention in a no-flow state is basically to rotate the pump and the internal fluid. It is a low-energy state with no load, no cavitation, and no fluid recirculation. This is the same state as when the suction hose of a vacuum cleaner is blocked, the rotation speed increases, the current decreases, and the load (moving air) is eliminated. As the rotation speed increases, the CEMF (Counter Electromotive Force) (back electromotive force) increases, and electrical resistance increases, which reduces the current and lowers costs.

[0005] No other fluid pump currently on the market offers the performance of the present invention. Furthermore, the pump of the present invention has a size-reducing flow path that increases pressure as the fluid moves through the flow path. These features make the pump of the present invention ideal for water desalination and other applications. Additional advantages and features of the present invention are further described below. Summary of the Invention

[0006] The present invention provides an energy-saving fluid pump that includes a convergent housing, a fluid diffuser, and a fluid densifier. The components, except for the fluid densifier, are connected and fixed so that they rotate together as a sealed unit. Because fluid constantly increases in pressure as it moves through the energy-saving fluid pump, cavitation is not possible within the convergent housing. Fluid exiting the fluid diffuser is immediately sheared by the stationary fluid densifier and directed downward to the center of rotation of the convergent housing, where it exits the convergent housing without rotating. The fluid densifier increases the pressure of the fluid passing through it until the fluid is directed to the outlet of the housing. [Brief explanation of the drawings]

[0008] All drawings are for the purpose of illustrating particular versions of the present invention and are not intended to limit the scope of the present invention.

[0009] The present invention is an energy-saving fluid pump that can prevent cavitation, recirculation, and motor lock while saving energy. The present invention can transport low-viscosity fluids, such as water and fuel. Its primary applications are water desalination and propulsion, where high pressure, high capacity, and reduced energy usage are important. As shown in Figures 1 to 4, the present invention may be composed of a fluid diffuser 7, a fluid densifier 13, and a convergent housing 1. The fluid diffuser 7 improves the efficiency of the present invention by expanding the fluid inflow. The fluid densifier 13 shears the fluid flow from the fluid diffuser 7, increasing the fluid outflow pressure. The convergent housing 1 surrounds the fluid diffuser 7 and the fluid densifier 13, facilitating the outflow of pressurized fluid without loss of fluid pressure or cavitation. Furthermore, the convergent housing 1 facilitates the transmission of torque to the fluid diffuser 7 to operate the present invention.

[0010] The overall configuration of the aforementioned components allows the present invention to transport low-viscosity fluids while saving energy, preventing cavitation, and maintaining high-pressure output. As shown in FIGS. 5 to 8 , the densifier 13 includes a densifier body 14, multiple densifier inlets 17, a densifier outlet 18, and multiple spiral flow channels 19. The densifier body 14 also includes a first densifier surface 15 and a second densifier surface 16. The convergence housing 1 includes a housing inlet 2 and a housing outlet 3 for fluid flow within the convergence housing 1. The fluid diffuser 7 and the fluid densifier 13 are rotatably mounted relative to each other so that the fluid diffuser 7 can rotate. However, the fluid densifier 13 does not rotate with the fluid diffuser 7. Furthermore, because the fluid diffuser 7 and the fluid densifier 13 are disposed within the convergence housing 1, the fluid diffuser 7 and the fluid densifier 13 are sealed within the convergence housing 1. Therefore, no sloshing occurs within the convergence housing 1 during or after operation.

[0011] As shown in Figures 6-8, the first densifier surface 15 and the second densifier surface 16 are positioned opposite each other around the center of the densifier body 14, forming the disk shape of the densifier body 14. A plurality of densifier inlets 17 extend (traverse) from the first densifier surface 15, through the densifier body 14, and to the second densifier surface 16 to enable fluid flow through the densifier body 14. The plurality of densifier inlets 17 are distributed around the periphery of the densifier body 14 and direct the flowing fluid from the periphery to the center of the densifier body 14. The densifier outlets 18 and the plurality of spiral channels 19 each extend from the second densifier surface 16 into the densifier body 14 to enable shearing of the flowing fluid. The spiral channels 19 are arranged radially around the densifier outlet 18 to shear the fluid flowing through the densifier body 14. Furthermore, the number of spiral channels 19 corresponds to the number of densifier inlets 17. As shown in FIGS. 3 to 5 , the housing inlet 2 is in fluid communication with the densifier inlets 17 through the fluid diffuser 7, so that the flowing fluid is expanded before reaching the fluid densifier 13. As the fluid flows from the rotating fluid diffuser 7 to the stationary fluid densifier 13, shearing of the fluid occurs, which increases as the fluid flow decreases. This allows for increased fluid pressure and rotational speed without adding load to the system, thereby saving energy. Each of the densifier inlets 17 is in fluid communication with the densifier outlet 18 through a corresponding spiral channel of the spiral channels 19, allowing the sheared fluid to exit the densifier body 14. Additionally, densifier outlet 18 is in fluid communication with housing outlet 3, allowing pressurized fluid to exit convergence housing 1. Densifier outlet 18 is slightly smaller in volume than the plurality of spiral passages 19 in order to maintain high pressure while directing the fluid back to the center of convergence housing 1 and out to the external piping system.

[0012] To prevent operational problems, such as motor lock, encountered in conventional pumps, the present invention uses a different method to drive the rotation of the fluid diffuser 7. The convergence housing 1, the fluid diffuser 7, or both may be driven by external means or may be an integral part of the drive means. In some embodiments, the present invention may further include a magnetic coupling 21 to enable the fluid diffuser 7 to be driven by an external electromagnetic motor. As shown in FIG. 16 , the magnetic coupling 21 includes a coupling rotor 22 and a coupling stator 23. As previously described, the fluid diffuser 7 is rotatably mounted within the convergence housing 1, and the fluid densifier 13 is stationarily mounted within the convergence housing 1. In this embodiment, the fluid diffuser 7 is the coupling rotor 22. Meanwhile, the coupling stator 23 is external to the convergence housing 1 and is positioned adjacent to the fluid diffuser 7, connecting the present invention to the external electromagnetic motor. Additionally, the coupling stator 23 is operatively coupled to the coupling rotor 22, and the coupling stator 23 is used to magnetically rotate the coupling rotor 22. For example, the magnetic coupling 21 may utilize multiple magnetic devices, such as magnetic bushings, externally connected to the fluid diffuser 7 or the convergence housing 1.

[0013] In another embodiment, the pump of the present invention may utilize an external mechanical means to drive the fluid diffuser 7. The external mechanical means may be an external motor, an electric or oil-fueled engine, or the like. As shown in FIGS. 12 and 13 , the present invention may further include a pump drive coupling 20 for rotating the fluid diffuser 7 at a desired rotational speed. The pump drive coupling 20 may be a geared belt or gears. Unlike the embodiment with the magnetic coupling 21, the fluid diffuser 7 is stationary mounted within the convergence housing 1, so that the convergence housing 1 rotates with the fluid diffuser 7. On the other hand, the fluid densifier 13 is rotatably mounted within the convergence housing 1, so that the fluid densifier 13 does not rotate with the convergence housing 1. The pump drive coupling 20 is located near the housing outlet 3. Furthermore, the pump drive coupling 20 is torsionally and externally connected to the convergence housing 1 to transmit external torque to the convergence housing 1. Thus, when the convergence housing 1 rotates, the fluid diffuser 7 rotates, but the fluid densifier 13 remains stationary.

[0014] Additionally, the present invention may utilize an integrated mechanical means for rotating the fluid diffuser 7 within the convergence housing 1. As shown in FIGS. 14 and 15 , the present invention may further include an electric motor 24. The electric motor 24 includes a motor rotor 25 and a motor stator 26. Similar to the embodiment with the magnetic coupling 21, the fluid diffuser 7 is rotatably mounted within the convergence housing 1, and the fluid densifier 13 is stationarily mounted within the convergence housing 1. Additionally, the electric motor 24 is disposed within the convergence housing 1, thereby allowing the electric motor 24 to be coupled to the fluid diffuser 7. The motor stator 26 is fixedly connected to the convergence housing 1, and the motor rotor 25 is torsionally connected to the fluid diffuser 7. Thus, when the electric motor 24 is activated, the motor rotor 25 rotates about the motor stator 26, rotating the fluid diffuser 7 at a desired rotational speed. In other embodiments, the present invention may utilize other drive means to rotate the convergence housing 1, the fluid diffuser 7, or both, to a desired number of rotations.

[0015] To increase the efficiency of the fluid diffuser 7, the fluid diffuser 7 is designed to significantly increase the pressure of the fluid flowing through it. As shown in FIGS. 9 to 11 , the fluid diffuser 7 may include a diffuser body 8, one or more diffuser passages 11, and fluid receiving holes 12. The diffuser body 8 further includes a first diffuser surface 9 and a second diffuser surface 10. The first diffuser surface 9 and the second diffuser surface 10 are positioned opposite each other on the diffuser body 8, forming a disk-shaped diffuser body 8. The fluid receiving holes 12 traverse the axial direction from the first diffuser surface 9 through the diffuser body 8 to the second diffuser surface 10, directing the fluid flowing through the diffuser body 8. One or more diffuser passages 11 traverse the diffuser body 8 from the second diffuser surface 10 toward a fluid densifier 13. Furthermore, the one or more diffuser passages 11 are arranged radially around the fluid receiving hole 12 to match the arrangement of the multiple densifier inlets 17. The one or more diffuser passages 11 decrease in size outward, constantly building up pressure. As shown in FIG. 9 , the cross-sectional area of ​​the one or more diffuser passages 11 contracts along its length, increasing in size closer to the fluid receiving hole 12 and decreasing in size closer to the periphery of the diffuser body 8. Furthermore, the housing inlet 2 is in fluid communication with the fluid receiving hole 12. The fluid receiving hole 12 is also in fluid communication with the one or more diffuser passages 11. Therefore, the inflow of fluid is directed toward the one or more diffuser passages 11. Finally, each of the one or more diffuser passages 11 is in fluid communication with the multiple densifier inlets 17, so that the expanded fluid flows into the fluid densifier 13.

[0016] In the present invention, the fluid diffuser 7 may further include an annular passage 29 to keep the fluid flowing without sloshing. As shown in FIGS. 5, 9, and 11, the annular passage 29 extends from the second diffuser surface 10 into the diffuser body 8, allowing the annular passage 29 to be part of the diffuser body 8 without interfering with the rotation of the diffuser body 8. The annular passage 29 is concentrically disposed around the fluid receiving hole 12, and the annular passage 29 is disposed on the outer periphery of the second diffuser surface 10. Therefore, as the diffuser body 8 continues to rotate, as shown in FIG. 5, the expanded fluid continues to flow from one or more diffuser passages 11 into the multiple densifier inlets 17.

[0017] To keep the convergence housing 1 completely sealed to prevent fluid sloshing, the convergence housing 1 is designed to fit snugly around the fluid diffuser 7 and the fluid densifier 13 and prevent the fluid densifier 13 from rotating. As shown in FIGS. 1 to 4 , the convergence housing 1 may further include a first housing 4 and a second housing 5 for separately housing the fluid diffuser 7 and the fluid densifier 13. The housing inlet 2 is integrated into the first housing 4, and the housing outlet 3 is integrated into the second housing 5. The first housing 4 and the second housing 5 are disposed on opposite sides of the convergence housing 1 to match the fluid diffuser 7 and the fluid densifier 13. Thus, the fluid diffuser 7 is disposed within the first housing 4, while the fluid densifier 13 is disposed within the second housing 5.

[0018] To further prevent energy loss, the second receiving section 5 may include a conical inner surface 30. As shown in FIGS. 4 and 5, the conical inner surface 30 forms a conical shape including a narrow portion 31 and a wide portion 32. The narrow portion 31 is positioned adjacent to the housing outlet 3, and the wide portion 32 is positioned adjacent to the fluid diffuser 7 and accommodates the diffuser body 8. Furthermore, the densifier body 14 tapers from the first densifier surface 15 to the second densifier surface 16 so that the densifier body 14 fits within the second receiving section 5. Thus, the conical inner surface 30 is coaxial with the densifier body 14. As the fluid exits the densifier outlet 18, it enters the second receiving section 5, which is smoothly open and has no tow, vanes, or traps. Thus, no centrifugal force is exerted again on the flowing fluid as it slips back through the center of the second housing 5. In other embodiments, the second housing 5 may include a non-conical inner surface to match a different shape of the densifier body 14.

[0019] Finally, to stationary the fluid densifier 13 within the convergence housing 1, the present invention may include a strut assembly 6. As shown in FIG. 17 , the strut assembly 6 enters the convergence housing 1 through the housing inlet 2, passes through the fluid receiving hole 12 of the fluid diffuser 7, and is positioned on the first densifier surface 15 so as not to impede the rotation of the fluid diffuser 7. The fluid densifier 13 is distally connected to the strut assembly 6 such that the strut assembly 6 supports the fluid densifier 13. Furthermore, the strut assembly 6 is oriented perpendicular to the first densifier surface 15, and the strut assembly 6 is also axially positioned on the first densifier surface 15 so that the convergence housing 1 can rotate while the fluid densifier 13 remains stationary. By placing the primary system loads on the fluid densifier 13 and absorbing them on the strut assembly 6 rather than on rotating parts, the pump of the present invention maintains energy conservation relative to the flowing fluid. In some embodiments, the strut assembly 6 may include a torsion strut 27 and a strut shaft support 28. The strut shaft support 28 is located near the housing inlet 2. The strut shaft support 28 is rotatably and externally connected to the convergence housing 1, allowing the convergence housing 1 to rotate independently of the strut shaft 28. The torsion strut 27 is connected between the first densifier surface 15 and the strut shaft support 28 to hold the densifier body 14 stationary and resist loads on the densifier body 14 that may cause it to twist or translate within the convergence housing 1. In other embodiments, the pump of the present invention may utilize a different mechanism to hold the fluid densifier 13 stationary within the convergence housing 1.

[0020] Although the present invention has been described in relation to its preferred embodiments, it should be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
